In this letter, a new reliability-based iterative
majority-logic decoding (RBI-MLGD) algorithm that computes
the extrinsic information of previous iterations of the variable
node is proposed. This decoding algorithm is called historicalextrinsic
reliability-based iterative decoder (HE-RBID) and improves
the bit-error-rate performance of the previous RBI-MLGD.
HE-RBID is particularly interesting for codes with a low degree of
variable node, where traditional RBI-MLGD algorithms do not
provide a good behavior. HE-RBID ensures a good performance
without searching for the minimum at the check node and only by
exchanging 1-bit messages between variable and check nodes.[-]
